Application tiled July 21,1900. Serial No. 24,435. (No model.)

T @ZZ whom, t may concern:

Be it known that l, CHARLES H. HALL, a citizen of the United States, residing at Frankfort, in the county of Clinton and State of Indiana, have invented a new and useful Corn- Planter, ot which the following is a specification.

)1y invention is an improved corn-planter, and relates particularly to the mechanism for reciprocating the bar that operates the seedslides, the object of my invention being to effect improvements whereby t-he stroke of the reciprocatine` bar may be regulated at will and whereby the seed-slides are positively operated under all conditions and the distance between the planted hills may be predetermined.

My invention consists in the peculiar construction and combination of devices hereinafter fully set lorth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view ot the corn-planter embodying my improvements. Fig. 2 is a detail Vfront elevation of the same. Fig. 3 is a detail perspective view showing the parallel guides, a portion of the operating-bar, and the adjustable tappet-yokes which travel on the said guides and support the said bar. Fig. el is a detail top plan View of the same, together with the cross-head and pitman. Fig. 5 is a detail sectional View taken on the line a d of Fig. 2. Fig. 6 is a similar view taken on the line b Z) of Fig. 2.

The trame 1 of the corn-planter is of the usual construction and supports the seedboxes 2, in which operate seed-slides, (indicated at 3 in Fig. 2,) which seed-slides may be of any suitable construction and form no part of my present improvements. The seedslides are actuated by a reciprocating bar 4, as is usual in machines ot this class, and my improvements are limited to means for actuating the said operating-bar.

The shaft or axle ,whicl1 supports the rear portion ot' the frame 1, is provided with the usual traction and supporting wheels 6, and on the said shaft is a loose sprocket-wheel 7, which when engaged by the clutch S is fast to and rotates with the shaft 5. The said clutch may be thrown into or out of engagement with the sprocket-wheel 7 by a lever 9, which is within reach of the driver stationed on the seat 10.

A vertical standard 11 is bolt-ed on the rea r side of the cross-bar 12 oi the machine-frame, as at 13, and said standard is provided at its upper end with a bearing14, in which is journaled a shaft 15. Said shaft has at its outer end a sprocket-wheel 16, which is connected to the sprocket-wheel 7 by an endless sprocketchain 17, and at the inner end of the said shaft 15 is a beveled pinion 1S. A vertical standard 19 is also'secured on the rear side of the c1'oss-bar12 by a bolt 20, said standard being at a suitable distance from the standard 11 and connected thereto by a link-bar 21 on the rear side of standards 11 19 and secured thereto by bolts 22 A brace-bar 24, has its upper end secured on the bolt 23, and said bracebar extends inwardly and is inclined downwardly and has its lower end bolted to the rear side of the cross-bar 12, as at 25. In the upper end of the standard 19 is a bearing 26, which is at right angles to the bearing 11i, and in which is jonrnaled a stub-shaft 27, that is provided at its 'front end with a crankwheel 28. On the rear side of the said crankwheel is a beveled gear-wheel 29, which is engaged by the bevel-pinion 1S. A c1ank-pin is secured to the cranlnwheel 2S at any required distance from the center thereof.

A pair of parallel guide-bars 31 are secured at a suitable distance above the cross-bar 12 by vertical brackets 32, the said brackets having their lower portions bolted on the front and rear sides of the cross-bar 12, as at 33. The ends ofthe guide-bars 31 pass through openings in the upper ends of the bracket-s 32 and are provided with nuts or caps 34C, which are screwed on the threaded extremities of ,the guide-bars,as shown. Apairo'f U shaped tappet-yokes 35 engage and slide upon the guide-bars 31 and depend therefrom, and the said tappet-yokes support the reciprocating bar yl, which operates the seed-slides, and are adjustably secured thereon by means or". bolts or screws 3G. A cross-head 37 is channeled on opposite sides to receive the guide-bars 31 and is supported by and travels on the said guide-bars. A pitman 38 has one end attached to the'c1ankpin 30 and the other ond IOO :5 appropriate tappet-yoke.

2o bar 4.

attached to the cross-head, as at 39, and it will be understood that the cross-head is reciprocated When the machine is in operation and at 'points near the ends of its stroke will engage the tappet-yokes 35, and thereby irnpart reciprocating motion to the operatingbar 4. The said bar will be moved in one direction as the cross-head completes its stroke in one direction, Will remain stationro ary while the cross-head is traveling in the op` 2 5 description and by reference to the drawings that my improved means for operating the bar 4 may be att-ached to and used upon a corn-planter of any existing type in which the seed-slides are actuated by reciprocating 3o bars, the standards l1 and I9 being detachably secured to the cross-bar l2 by means of bolts, and the brackets 32, which support the guide-bars, being also detachably secured to the cross-bar by means of bolts.

Having thus described my invention, I claiml. In a corn-planter, the combination with a seed-slide-operating bar, of a pair of tappetyokes adjustable thereon and secured thereto, parallel guides on which said tappet-yokes reciprocate, a cross head on said guides adapted to actuate the tappet-yokes at the limits of the strokes of the cross-heads, a crank-Wheel, means to rotate the same, and a pitman connecting said crank-Wheel to said cross-head, substantially as described.

2. In a corn-planter, the combination of a seed-slide-operating bar, a pair of tappetyokes adjustable thereon and secured thereto, parallel guides on which said tappet-yokes reciprocate, a cross-head on said guides, a crank-wheel, a pitman connecting said crankwheel to said cross-head, a counter shaft geared to the shaft which carries the crankwheel, said counter-shaft having a sprocketwheel, a sprocket-wheel on the driving-shaft ofthe planter, an endless sprocket-chain connecting said sprocket-wheels, and a clutch to lock the driving sprocket-wheel to and release the same from the said driving-shaft, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

CHARLES I-I. HALL.
